Always, we have to understand a golden rule that the Qur'an is always right even there is a contradiction between science and Qur'an because one day the rightness of the Qur'an will be clear to all people.
The above is pretty much why no religion will ever provide the progress the sciences or the classical liberal arts have provided.

Abstract In Question (Note how they're so specific and careful about their claims):

In the abstract alone, the others hint that there's a "U-Shaped" relationship between sleep and mortality. People have known for a while now that either too much or two little sleep can have serious health consequences. The medical community has been adequately warning about both and the importance of going over your sleeping habits with your medical professional especially when there are sudden changes. There's a growing body of research shaping our understanding of what disrupt sleeps, what those short-term, and long-term consequences are and addressing them has required nothing supernatural.
If you can remove something that's been declared necessary and still see the same results, then what you removed was not associated with the outcome in anyway. Couldn't we have replaced Islam in the claim above (which is already shaky) with any culture or religion that also has night or early morning rituals? Could we then say the following:
Always, we have to understand a golden rule that the <Insert Divine Book,Being, or Imperative> is always right even there is a contradiction between science and <Insert Divine Book,Being, or Imperative> because one day the rightness of the <Insert Divine Book,Being, or Imperative> will be clear to all people.
What happens with long settled issues that aren't in favor of religions and will not be changing anytime soon? Where's the self-correction? Where's the progress?
Even though it was hypothetical, there's a group of scientific fields that study cultural convergences when trying to solve problems everyone has to deal with, adapting to similar conditions, while using pretty much the same brains furnished to members of our species.
Science needs no faith. It only starts with the idea that maybe something in whole or in part can eventually be understood, and goes through a robust, observation based, and self-corrective approach to try to accomplish that goal. It requires no faith because anyone can practice it, anyone can verify or disprove previous understandings or claims, and anyone can practice it with or without religious belief and still get the same results (a bit of an oversimplification but the main idea is important).
